HOOF-PAD.

SPECIFICATION forming part of Letters Patent No. 690,231, dated December 31, 1901. Application led October I7, 1901. Serial No. 78,956. (No model.)

T0 all whom, it may concern.-

Be it known that I, JOHN CAMPBELL, a subject of the King'of Great Britain, and a resident of the city of New York, borough of- Manhattan, in the county and State of New York, have invented a new and Improved Hoof-Pad, of which the following is a full, clear, and exact description.

This invention relates to'a hoof-pad which is especially adapted for use by horses having corns or navicular trouble. These corns in most instances form around the frog of the hoof as contradistinguished from on it, and the present invention relates to a form o f pad which will relieve a hoof afflicted in the manner mentioned by placing the weight and concussion on the heel and frog of the hoof.

This specification is a specific description of one form of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming apartof this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a bottom view of a pad embodying my invention. Fig. 2 is a section on the line 2 2 of Fig. l.' Figs. 3 and 4 are sections on the lines 3 3 and 4 4, respectively, of Fig. l; and Fig. 5 is a top view of a pad with the backing removed.

a indicates the backing, which is preferably in the form of a leather sheet, on the under side of which the shoe (not shown) is fastened by devices passing through the backing into the hooi". The pad b lies within the shoe and in the instance shown entirely covers the area inside thereof. The outer edges of the pad conform to the inner margin of the shoe, and the pad has recesses h at the sides, in which are received the heels of the shoe.

These recesses are located forward of the heel at the quarters of the hoof, and the pad is therefore adapted for use in connection with shoes which extend only to the quarter. The pad is fastened by cement or stitching or by any other means desired to the backing a,

and the top of the pad is formed with a cav,

ing part d, on a plane with the outer surface d', on which latter the wall of the hoof is afforded a bearing. The central bearing-surface d is located directly under the frog, so as to receive thereon part of the weight of thehorse, and extends forwardly to a point beyond the quarter. The passages c lead from the sides of the cavity c to the heel of the pad and open into' the atmosphere, thus permitting the free circulation of air into the cavity, which keeps the air therein cool and prevents the hoot' from becoming heated. Now it will be seen that with a pad of this construction the weight and pressure are sustained by the'frog-bearing d and the surface CZ outside the air-chamber, while the said chamber permits the leather backing to yield if borne upon by a corn on the hoof at the sides of the frog.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A hoof-pad, comprising a backing of leather, and a facingformed of yielding material and having a cavity in its upper face, said cavity extending along the sides and front of the frog of the hoof, the pad having a solid part located centrally and running from the solid heel part of the pad forwardly beyond the quarter, said central solid part of the pad lying under the frog of the hoof to form a bearing therefor.

2. A hoof-pad, comprising a backing of leather and a facing formed of yielding material and having a cavity in its upper face, the cavity extending along the sides and front of the frog of the hoof, and the pad having a solid part located centrally and running from the solid heel part of the pad forwardly, the central solid part of the pad lying under the frog of the hoof to form a bearing therefor, and the pad also having passages therein leading from the rear ends of the sides of the cavity to the heel of the pad and opening into the atmosphere, for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN CAMPBELL.
